 **NOTE** : Some librairies may be missing, you need to install it one by one (test to launch ./et.x86 and see missing libs)
 
+## Create a systemd service (server creation **ONLY**)
+
+In order to launch the server properly, a systemd service is a right solution instead of the **serverctl** sh script. Todo so :
+
+* put the **[wolfenstein-et.service](./service/wolfenstein-et.service)** file in **/etc/systemd/system** directory (must be **root**)
+* replace `<linux_user>` and `<path_to>` placeholder with your configuration
+* enable the service (on reboot the service will autostart)
+```bash
+# as root
+systemctl enable wolfenstein-et
+```
+* put the **[launch_server.bash](./service/launch_server.bash)** wherever you want (do not forget exec rights for your `<linux_user>`)
+* start the service 
+```bash
+service wolfenstein-et start
+```
+* check the service status
+```bash
+service wolfenstein-et status
+```
+
